Inventor: SATO YUMIKO
IPC: G06F9/44
Filed: 1990-02-28
Abstract: PURPOSE:To select an optimum plan at a starting time point by setting a target- based plan model based on the plan setting conditions and the future estimating knowledge. CONSTITUTION:A question generating means 2 performs the guidance in order to acquire the information needed for the plan setting conditions of a develop ment project via a data input/output device 1. An answer is given to a plan setting means 4 via the device 1 and an answer reception means 3. A target- based planning means 5 generates a plan model based on the answer and the plan setting knowledge of the means 4 and estimates the state of the project at a target time point. This estimated project is shown by a target-based plan display means 6 via the device 1. Then the means 5 performs the correction with a correction request received from the means 3. A standard plan generating means 7 produces a standard plan model and diagnoses the plan. If this diagnos tic result shows that the project is appropriate as a plan via a plan diagnostic result generating means 9, this project plan is displayed through the device 1. Thus, it is possible to select an optimum plan at a starting time point.

Title: Controlling method for pulse width of three-phase voltage type invertor
IPC: H02P27/06
Filed: 1992-03-09
Abstract: PURPOSE:To reduce a switching loss and the electromagnetic noise generated when an invertor device is operated, by lessening the number of times of switching of a controllable element. CONSTITUTION:A voltage instruction value is converted into a vector Vi and the vector Vi is divided by a vector divider 412 into two vectors VA and VB of which phase angles holding the vector Vi between are different by pi/3 from each other. Vector selectors 416A and 416B selects a zero vector obtained by switching one phase of each of the vectors VA and VB. Switches 420A and 420B switchover the vectors VA and VB and the zero vector alternately at time intervals corresponding to the magnitudes of VA and VB components of the vector Vi. A timer part 419 makes a switch 420C operate so that the rate in an output time of the vectors VA and VB within a unit time be a value corresponding to the vector Vi.

Title: Rotary electric machine
Inventor: NAKAHAMA YOSHIFUMI
IPC: H02K3/24
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a rotary electric machine which can be improved in energy density due to the temperature of a winding at the center of a stator core which becomes lower due to an increased overall heat transfer coefficient from the winding at the center of the stator core to a cooling gas from the conventional value and has a small machine size. SOLUTION: A plate-like heat pipe 26 is arranged in a single or a plurality of steps between a slot bottom-side winding 3a and a slot opening-side winding 3b of the end of a winding and the end section protruded from the end face of a stator core 2 is tilted or formed in a bent section. Therefore, the overall heat transfer coefficient from the heat radiating section at the end section of the heat pipe 26 is removed, because a cooling gas smoothly flows without coming into contact with the internal surface of the pipe 26 and hardly forms a stagnated part. In addition, the heat radiating area of the end of the pipe 26 increases.
